Hello. For some reason I'm really not sure if I already know the answer or not. Still learning.

If I am receiving some small bitcoin donations - 15,000 to 35,000 sats per donation, then how do I know if that donation is from a KYC exchange or a non-KYC exchange?

Does the answer depend on the address of the sender?

I'm still a bit confused about this. I don't want to mix up my KYC and non-KYC coins.

Thanks
